Packaging



Patented Mar. 24, 1942 'r 115i y PACKAGING William 0. Ballard andClifford' J. Kraemer, Toledo, Ohio 3 Claims.

This invention relates to packaging.

This invention has utility when incorporated in packages, moreparticularly of the multi-ply wall type, and incorporating therewith auseful novelty as an attraction to purchasers apart from the goodscontained therein.

Referring to the drawing:

Fig. 1 is a front elevation of a closed package embodying the inventionherein;

Fig. 2 is a view similar to Fig. l but with the closure of the packagein open position;

Fig. 3 is a plan view of the package of Fig. 2, having theeye-attracting element removed and ready to open the inner envelope;

Fig. 4 is a section transversely through the upper portion of thepackage of Fig. l;

Fig. 5 is plan view of a modified type or soft package, embodying theinvention herein;

Fig. 6 is a perspective view of a multi-ply wall soft package embodyingthe invention herein, having the outer ply in open position; and

Fig. 7 is a plan view of a package embodying the invention hereinwherein the resilient sealbreaking member has its free leg ofalternative form herein shown as a helix.

Container I is provided with closure or cover 2 hinged therewith.Preferably this primary container I is a sheet metal can providingpocket 3 wherein material Il may be directly deposited or if suchmaterial is subject to drying or is affected by climate, light or otherweather conditions, such material may be sealed in inner or secondarycontainer or envelope 5 which in turn may be placed in the primarycontainer I.

The inner container or envelope 5 may be formed from a sheet of iiexiblematerial such as paper, Cellophane, or the like into a pocket, thesealing of which is by folds 6 held by adhesive 7.

In multi-ply wall packages of this type, the usual practice is to sealthe contents i within the soft or fragile envelope 5 and then place suchinto the comparatively rigid outer container I as an armor againstcrushing or other detrimental actions. There is thus provided asubstantial package suitable for long-time storage of perishable or easydamaged products common in packaging tobacco, foodstuffs, condiments,cleaning preparations, etc.

The invention herein is primarily directed to the provision of anadditional utility to the container as well as to invite desire thereforin the container itself beyond the particular appeal of the contents. Tothis end staff or pipe cleaner 8 comprising a resilient wire core 9mounting fibrous material II), is bent into a U-shape, the

extent' of the bending being less than suicient to hold its U-shape withlegs I'I, I2, thereof in the same plane, so that if' the legs are forcedinto the same plane, the wire Sis under torsion and when the holdingpressure is released, the member will spring to move into its free ornon-torsion position.

In sealing a fold 6, leg II of the member 8 may be embraced thereby tofix this leg in such fold with the leg I2 extending free therefrom. Withbend I3 a smooth arc and not crimped, the free leg I2 will tend toextend upwardly from the envelope 5. With the envelope 5 in the can I,closing of the cover 2 will force the free leg I2 downwardly and placesuch under tension. When the cover 2 is shifted to open position, theleg I2 will spring upward to extend out of the container I toward theuser providing a readily gripped terminus which may be pulled from thecontainer in turn initially opening the folds B so that the innerenvelope may then be readily and completely opened to expose thecontents 4. When a particular type of opening element, such as a pipecleaner, is used in connection with tobacco dispensing, it has apeculiar utility in that the user of the tobacco is provided with meansfor readily opening the package and in addition thereto the openingmeans has additional utility as a duct cleaner before being discarded. Apipe cleaner also has utility when used as the opening element inpackages containing cleaners of various types, as the member 8 may besaturated with the cleaner to be applied to confined places otherwisehard to reach.

As an additional eye-attracting utility, legend carrying tag I4 may beslipped on the free leg I2 so that as the package is opened, the legendwill be sprung toward the user insuring it to be observed. The tag I4may contain instructions for using the product, slogans or advertisingmatter for other or kindred items.

In some instances it may be desirable to market the product in a softpackage comprising a single ply envelope I5 having themember 8 attachedthereto by having leg II embraced by a fold 6 and the arc I3 so bent asto have the free leg I2 rest snugly against the package. The member 8may rst be straightened (Fig. 5) and then pulled up from the packagewhich will cause such to be opened.

Again, in some instances, the invention may be incorporated in amulti-ply soft package (Fig. 6) and the member 8 fixed with a fold of aninner wrapper I6 While outer wrapper I'I may encase the contents, anynumber of'wrapping plies, and the member 8 which may be bent to liesnugly against the inner container without torsion or be under tensions0 as to spring outwardly when the outer wrapper II is opened. Thevarious plies may be paper, foils, cellophane, or other like materials.

The member 8 may have its free leg I2 bent into various patterns ordesigns such as a spiral, an initial or such may be coiled into a helixI8 so as the outer wrapper is removed the terminus I9 will springoutwardly.

The inherent resiliency of the common pipe cleaner is such that it maybe so bent as to have the free leg I2 spring outwardly from an openedpackage even though such has been packed for a considerable period oftime.

What is claimed and it is desired to secure by United States Lette-rsPatent is:

1. A can having a cover, a material housing envelope in said canprovided with a fold as a seal therefor, a resilient U-shaped memberbetween said cover and envelope providing a pair of legs, one of saidlegs embraced by said fold and the other leg free to spring outwardlyfrom amzos said can upon shifting said cover to can-open position.

2. A tobacco package embodying a can having a cover, a tobaccocontaining envelope in said can having a fold providing a seal therefor,a pipe cleaner formed to provide a resilient member and held undertorsion between said cover and envelope when said cover is incan-closing position, a portion of said member being embraced by saidfold, and an additional portion being free to spring outwardly from saidcan when the cover is shifted to can-open position.

3. A package providing inner and outer containers one Within the other,said inner container providing a fold as a seal therefor, and a U-shaped resilient element providing a pair of legs, one embraced by saidfold, whereby removal therefrom opens said fold, said inner package andU-shaped element being enveloped by the outer package to hold theU-shaped element under torsion.
